将成交量组合公式中参与度大于50时设为选股公式 参与度为主买占主买+主卖总和的比例



成交量:V,COLOR00ffff;//线性不输出

STICKLINE(C>=O,0,V,8,0),COLOR0000ff;

STICKLINE(C<O,0,V,8,0),COLOR00ff00;

RSV:=(CLOSE-LLV(LOW,21))/(HHV(HIGH,21)-LLV(LOW,21))*100;

K:=SMA(RSV,7,1);

D:=SMA(K,3,1);

J:=3*K-2*D;

STICKLINE(CROSS(J,7.6),HHV(V,20),0,4,0),colorwhite;

AT:=IF(CAPITAL=0,AMOUNT/1000000,VOL/CAPITAL*100);

ATM1:=EMA(AT,5);

ATM2:=MA(AT,13);

阶段地量:=AT<REF(LLV(AT,25),1) AND  ATM1<ATM2;

STICKLINE(阶段地量,0,V,8,0),COLORff5500;

BB:=VOL/((HIGH-LOW)*2-ABS(CLOSE-OPEN));

买:=OUTVOL;

卖:=INVOL;

主动买:=IF(CLOSE>OPEN,BB*(HIGH-LOW),IF(CLOSE<OPEN,BB*((HIGH-OPEN)+(CLOSE-LOW)),VOL/2));

主买:主动买/10000,colorred;//线性不输出

主动卖:=IF(CLOSE>OPEN,0-BB*((HIGH-CLOSE)+(OPEN-LOW)),IF(CLOSE<OPEN,0-BB*(HIGH-LOW),0-VOL/2));

主卖:-主动卖/10000,colorgreen;//线性不输出

参与度:主买/(主买+主卖),colorffff00;//线性不输出

WW:=VOL/REF(VOL,1)>2;

GG:=C>O;

STICKLINE ((WW AND GG) OR (C>REF(C,1) AND C=O AND WW),0,VOL,3,0),colorffff00;

QQ:=C<O;

STICKLINE ((WW AND QQ) OR (C<REF(C,1) AND C=O AND WW),0,VOL,3,0),color009fff;

l0:50,colorred;


解答如下：
BB:=VOL/((HIGH-LOW)*2-ABS(CLOSE-OPEN));

主动买:=IF(CLOSE>OPEN,BB*(HIGH-LOW),IF(CLOSE<OPEN,BB*((HIGH-OPEN)+(CLOSE-LOW)),VOL/2));

主买:=主动买/10000;

主动卖:=IF(CLOSE>OPEN,0-BB*((HIGH-CLOSE)+(OPEN-LOW)),IF(CLOSE<OPEN,0-BB*(HIGH-LOW),0-VOL/2));

主卖:=-主动卖/10000;

参与度:主买/(主买+主卖)>50;
